U.S. supercomputers run by the federal government comprised five of the top 10 most powerful in the world, according to the latest list of the world’s top 500 supercomputers. Four Department of Energy systems and one run by NASA made the top 10 in a biannual ranking of the top 500 high-performance-computing systems. Japan’s K Computer and China’sTianhe-1A took the top two spots.
The DOE’s Cray supercomputer at the Oak Ridge National Laboratory–known as “Jaguar”–came in third place, with a performance of 1.75 petaflops per second. Rounding out the top five U.S. supercomputers are a DOE Cray computer called Cielo at No. 6; an SGI system called Pleiades at the NASA Ames Research Center at No. 7; a DOE Cray system called Hopper at No. 8; and a DOE IBM system called Roadrunner at No. 10.
